Shame showers down on the shoulders of the Royal Society leadership.
Paul Nurse, interviewed by the FT about whether @royalsociety.org should expel Musk said: "the institution should only expel fellows if their science proved “faulty or fraudulent or highly defective”". That implies the Society's Code of Conduct is utterly meaningless.

The Strange and Totally Real Plan to Blot Out the Sun and Reverse Global Warming
A 25-person startup is developing technology to block the sun and turn down the planet’s thermostat. The stakes are huge — and the company and its critics say regulations need to catch up.

Further to The Guardian's series promoting solar geoengineering, I'll note that most of the voices they platformed are the usual suspects, who are trying to make a name for themselves by growing their SRM research programmes -- they are stakeholders in growing the research

Apropos of The Guardian's recent all-out six part endorsement of developing solar geoengineering technology (and let's not pretend it's "just research") I wonder what @georgemonbiot.bsky.social thinks about The Guardian's whiplash U-turn on becoming an avid promoter of this false solution.

It has not escaped my attention that The Guardian has just published a six part series advocating strongly for developing solar geoengineering technology. It was even led by an editorial claiming "It's time to talk about solar geoengineering." This series is so one-sided, and so egregiously fails

@katharinehayhoe.com @michaelemann.bsky.social , @hausfath.bsky.social . I'm about to send this letter to The Guardian expressing concern over yesterday's SRM article which ignores how the fossil fuel industry could abuse Solar geoengineering R&D. Is this OK? Link follows.. /1 #ClimateCrisis

Yet another indication that Daniel is the right person to uphold the fight for progressive values in our district. He is the most experienced candidate, the one with the best plans, and the one who knows our district best having lived and worked here for years, including in government.
I am truly humbled to have the support of Jan Schakowsky in this campaign. She is an icon, a fierce and fearless warrior for our communities and a true friend.

Well put.
Everything we've made will break, buildings and streets will crumble, and cities will be abandoned. But the CO₂ we emit into the atmosphere will persist for centuries, and the climatic impacts will last longer than human civilization has existed. This is our legacy for the future.

Well put.
No, it's absolutely not "buying time," since CO2 that accumulates in the atmosphere continues to disrupt the climate for millennia. If you need solar geoengineering to avoid dangerous global heating, you need to keep it up essentially forever.
Any climate solution that begins “a secretive team of scientists is working on…” should probably end with “this won’t fix the real problem”.
Dimming the sun isn’t climate action — it’s avoidance, or buying time at best.

Trump and his MAGA enablers lied to Congress and launched illegal, unconstitutional strikes to facilitate regime change in Venezuela. Congress must reassert its war powers authority immediately to halt further military action before we’re pulled further into another senseless war.
